02' Marin Rocky Ridge Seatpost dia.

Anyone know what the seatpost size is on a 02' Marin Rocky Ridge? I've searched and searched, and came up with two different spec sheets for the same (17" 2002). 27.0mm, and 27.2mm. I measured with an older pair of calipers(standard, may or maynot be 100% accurate though), and converted to metric, and came up with 26.8mm.. Anyone know for sure? The guys at Marin aren't to eager to pull out the spec sheets for me.

That is f!!@#$$$%% ridiculous! Did you give them some lip service? How hard is it(even if you are to stupid to either know or remember a two year old bike) to look up or say you will call back when you get the answer. Unreal. That is customer disservice at its best. Rant, rant rant....Sorry I cant help either, btw.
